I'm guessing from your sweeping comment that you are unaware that quite often when dance tracks are made there are chilled versions of the tunes that are also remixed; for example Static Revenger - Happy People [Christian J Rohodes Remix] HERE or ATB -9pm (Till' I come) (Bent Remix) HERE and Kristine Blond - Love Shy - Sandgate Remix HERE - just to highlight your three examples.

Cheap compilation tracks? Not at all. Each one is an excellent chilled remix version of the more commercial 'dancy' track that you are probably thinking of
